PAPER-FOLDING MACHINE.

Application filed October a, 1923.. Serial No. 667,204.

invention relates to paper-folding ma chines, and more particularly to the transverse feeding frame thereof. The. object of thisinvention is the provision in a..paperfolding machine of a transfer appliance between the horizontal and vertical folding rollswhich is less liable to become clogged with crumpled signatures and which may be more readily cleared therefrom than is any appliance of this sortin the prior art.

Owing to the difficulty of obtaining com plete coact-ion between the initial sets of fold ing rolls and the right-angle transfer mechanism of a paper-folding machine, difficulty not infrequently is experienced through the piling up of signatures in the transfer frame, whereby it becomes jammed and the crum pled signatures are so tightly packed therein that the frame must be taken out of the folding machine and dismantled in order to clear it of the tightly packed paper. This necessarily involves considerable delay and expense which the present invention successfully obviates.-

In accordance with my improvements the transfer frame preferably is pivotally mounted adjacent to its lower edge within the paper-folding machine and a section thereof is movably mounted to insure better 31) operation and permit the ready removal of any signatures that may accidentally become jammed in said frame.

The details of this construction and advantages of its operation may be more readi- 35 1y explained in connection with the accompanying drawings, wherein:

Figure 1 is a transverse sectional view of a paper-folding machine equipped with my improvements and illustrating the rightangle feeding mechanism in elevation.

"* drawings I have employed the same character of reference to indicate similar part-s.

Referring lnitially to Fig. 2, the foldlng and buckling rolls, a, b, c and (Z are shownin association with the throats of their coacting folding plates'e and f, rearwardly broken away. From the rolls 0, d the signature passes immediately to the rolls g, h for directing it into the right-angle transfer ap-' pliance which is the construction herein specificallyclaimed. a a

Said appliance comprises a frame 2'v pivotec. at 2' within the folding machine to swing through anarc approximately of from the full line to the dotted line position; being held in its operative position by'means of the links 2'" and thumb nuts it. The frame is provided with a series of rods 7" rigidly mounted beneath the throat member j and an opposin series of rods 70 resiliently sup ported, together with the throat member 70 by means of the coiled springs/c, as well shownv in Fig. 3. derstood that the right-hand section of the throat is yieldingly mounted in a manner to improve the operation of said transfer appliance by affording it a slight resilience. Moreover, since the entire spring-mounted member may be depressed against the tension of the springs, any jamming of crumpled signatures accidentally occurring below the IOlls g, It, will be localized at the throat member 70. v

WVhen this accidentally occurs, it is extremely easy to remove the mass of signatures merely by releasing the links 2' and tilting the frame into its dotted line position of Fig. 2. For this purpose the main frame of the folding machine is of rearwardly open type as indicated in Figs. 1 and 2 in order to permit access to the downwardly tilted transfer appliance. As the frame is made readily yielding, the crumpled paper does not become so tightly jammed as is the case with ordinary folding machines not equipped with my improvements, while no disassembling of any portion of the machine is necessary in order to free it of the accumulated signatures.

The grooved guide Z provided for the righthngle transfer appliance is made vertically adjustable and is held in any adjusted position by the clamping screws Z. At the right ofsaid guide there are provided one or more paired rolls on, m between which the lower edge of the signature passes inorder to impel it toward the right and effect a right-angle fold in the lateral fold ing plate n, shown broken away in Fig. 1.

Although Ihave illustrated the conical coiled springs k for resiliently supporting From this, it will be un- Havin now described a 3a aer-t'oldin 1na-' chine equipped with the improvements of my present invention, which, however, is subject to more or less variations to adapt it for different classes of machines, I claim as new 10 and desire to secure by Letters Patent, to-

gether with such modifications as may be made therein by those ordinarily skilled in the art, the following:

1. The combination with a paper-folding 53 machine, of a transfer appliancev having relatively movable members, and resilient means substantially as set forth.

2. The combination withv a paper-folding machine having horizontal and vertical folding mechanisms, of an interposed transfer appliance comprising a frame liavingrelatively movable throat members, and yielding means associated with the movable throat member adapted to retain it in operative relation against such relative movement, substantially as set forth, 1

In testimony Wll-BIGOfI' do now affix my signature.

JOHN H. SHIPLEY.
